RETURN OF THE STINGRAY
Chevrolet is redefining modern performance with the all-new Corvette Stingray. And only a Corvette with the perfect balance of technology, design and performance can wear the iconic Stingray designation.
The 2014 Corvette Stingray is the most powerful standard Corvette model ever, with an estimated 450 horsepower (335 kW) and 450 lb.-ft. of torque (610 Nm). It is also the most capable standard Corvette model ever, able to accelerate from 0-60 in less than four seconds and achieve more than 1g in cornering grip.
The new Corvette Stingray is expected to improve upon the current model’s fuel economy of EPA highway fuel economy estimate of 26 mpg (13.6L/100km).
“Like the ’63 Sting Ray, the best Corvettes embodied performance leadership, delivering cutting-edge technologies, breathtaking design and awe-inspiring driving experiences,” said General Motors North America President Mark Reuss. “The all-new Corvette goes farther than ever, thanks to today’s advancements in design, technology and engineering.”
The all-new Corvette Stingray shares only two parts with the previous-generation Corvette. It incorporates an all-new frame structure and chassis, a new powertrain and supporting technologies, and a completely new exterior and interior designs.
The Stingray Coupe and Convertible share identical chassis tuning and performance technologies. They also share nearly-identical curb weights, as the only structural changes for the convertible model are limited to accommodations for the folding top and repositioned safety belt mounts.
Corvette Stingray highlights include:
- An interior that offers genuine carbon fiber and aluminum trim, hand-wrapped leather materials, dual eight-inch configurable driver/infotainment screens, and two new seat choices – each featuring a lightweight magnesium frame for exceptional support
- Advanced driver technologies, including a five-position Drive Mode Selector that tailors 12 vehicle attributes to fit the driver’s environment and a new seven-speed manual transmission with Active Rev Matching that anticipates gear selections and matches engine speed for perfect shifts every time
- An all-new 6.2L LT1 V-8 engine combines advanced technologies, including direct injection, Active Fuel Management, continuously variable valve timing and an advanced combustion system that delivers more power while using less fuel
- Lightweight materials, including a carbon fiber hood and removable roof panel on coupes; composite fenders, doors and rear quarter panels; carbon-nano composite underbody panels and a new aluminum frame help shift weight rearward for an optimal 50/50 weight balance that supports a world-class power-to-weight ratio
- A sculpted exterior features advanced high-intensity discharge and light-emitting diode lighting and racing-proven aerodynamics that balance low drag for efficiency and performance elements for improved stability and track capability
- An all-new, fully electronic top on the convertible that can be lowered remotely using the key fob
- Track-capable Z51 Performance Package, including an electronic limited-slip differential; dry-sump oiling system; integral brake, differential and transmission cooling; as well as a unique aero package that further improves high-speed stability.
“Stingray is one of the hallowed names in automotive history,” said Ed Welburn, GM vice president of global design. “We knew we couldn’t use the Stingray name unless the new car truly lived up to the legacy. The result is a new Corvette Stingray that breaks from tradition, while remaining instantly recognizable as a Corvette the world over.”
The new Corvette Stingray will be built at GM’s Bowling Green, Ky., assembly plant, which underwent a $131-million upgrade, including approximately $52 million for a new body shop to manufacture the aluminum frame in-house for the first time.
“We believe the Corvette represents the future of modern performance cars because it delivers more power, more driving excitement and better fuel efficiency,” said Tadge Juechter, Corvette chief engineer. “The result is better performance by every measure. The 2014 Corvette delivers the fastest acceleration, the most cornering grip, the most track capability, the best braking performance and what we expect to be the best fuel economy ever for a standard Corvette.”
Handcrafted, high-tech interior
The new Corvette Stingray interior blends fine materials and craftsmanship with advanced technologies that contribute to a more connected and more engaging driving experience, said Helen Emsley, interior design director.
“Every feature and detail in the interior is designed to enhance the driver’s connection to the Corvette,” Emsley said. “It starts with the fighter jet-inspired wraparound cockpit; continues to build with the smaller steering wheel, more supportive seats, and high-definition, configurable screens, and is finished in gorgeous materials.”
The smaller, 14.1-inch-diameter (360 mm) steering wheel fosters a more direct, immediate feel to directional inputs. The attention to the driver extends to the smallest details, including the flat, precise stitching on the steering wheel designed to provide a smooth, consistent feel.
Precise and elegant stitching also is seen in the available Napa leather trim on the all-new seats. Two seating choices will be offered: a GT seat for all-around comfort and a Competition Sport seat with more aggressive side bolstering that provides greater support on the track.
The frame structure for both seats is made of magnesium for greater strength and less weight than comparable steel frames. They’re also more rigid, contributing to the enhanced feeling of support during performance driving.
Additional performance-enhancing details in the interior resulted from designers’ “field trips” to GM’s Proving Ground in Milford, Mich., where high-performance driving experiences spurred the design and implementation of several features, including a steel-reinforced grab bar on the center console for the passenger and soft-touch materials on the edge of the console, where the driver naturally braces during high-load cornering.
High-performance driving also influenced elements of the configurable display screens and available head-up display, which vary depending on the driving mode, including the Track display inspired by the C6.R.
The performance-supporting elements inside the new Corvette Stingray are complemented by unprecedented attention to detail and build quality, including the sweeping arch motif over the driver cockpit trim and the seamless transition of the line from the instrument panel to the door.
All models feature a fully-wrapped interior, where every surface is covered with premium, soft-touch materials. Available materials, depending on the trim level, include Napa leather, aluminum, carbon fiber and micro-suede.
A blend of hand craftsmanship and machined precision is intended to ensure the fit, finish and ambience of the cabin is first-rate. The leather-wrapped instrument panel, for example, features hand-selected and hand-stretched materials for better grain matching with stitching performed by robots that deliver perfect seams.
There’s even a micro-LED screen for the passenger’s climate control placed below the vent on the dash, away from the performance features on the instrument panel.
“To ensure the high quality of the interior, we spent time working on the line alongside the team that builds the Corvette every day at Bowling Green Assembly Plant,” said Ryan Vaughn, interior design manager. “And thanks to that collaboration between design, engineering and manufacturing, we were able to make adjustments that allowed us to maintain the integrity of the design, improve the assembly process and ultimately deliver what we believe to be a world-class interior.”
The differences in the Standard GT seat and the Competition Sport seat offered in the 2014 Chevrolet Corvette are similar to the everyday comfort of a well-tailored suit vs. the support offered by compression apparel athletes wear.
“Better seats topped our list for interior improvements, and we knew offering just one style would not cut it,” said Tadge Juechter, Corvette chief engineer. “Some Corvette drivers use the car for commutes, others as a grand tourer, and some drive it competitively. With two supportive seat options to choose from, drivers can pick the style that best suits their driving habits.”
Digital pressure-mapping, technology used to scan people’s backsides when seated, played a pivotal role in the development of the Corvette’s new Competition Sport seat, available as an option in December. Different seats last were offered in Corvette’s fourth generation – 1984-1996.
For the Competition Sport seat, the Corvette team took pressure-mapping technology to the test track to accurately measure driver bottom and back pressures during high velocity maneuvers. On most vehicle development programs pressure-mapping is only used for static impressions.
The technology involves taking a digital snapshot of a person’s back and rear-end pressure distribution over the seat surface, creating a map with more than 4,600 data points per second. The information is transferred to a computer that generates graphics illustrating how occupants are supported by the seat.
The new Corvette also was the first Chevrolet to use a new process for judging seat performance in addition to comfort, based on the subjective evaluations of test drivers of varying sizes, from large males to petite females.
For the new seats, the Corvette team used the advanced materials, including an all-new lightweight cast magnesium frame for greater strength. The frame’s rigidity and the seat’s hard back panel contribute to an enhanced feeling of support during performance driving.
The Sport seat was track tested and modified to provide the kind of bolster support needed for high-velocity maneuvers. The development team hand-modeled extreme bolsters out of duct tape and foam until they were satisfied with the seat’s track performance.
Back bolsters 35-mm deeper than those in the 997 generation Porsche Carrera S are approximately 35 percent deeper for more lateral support when making hairpin turns. The Corvette team also re-engineered the seat’s side airbag, moving it outside of the seat bolster to an attached but separate pod so that the seat could be slimmer, stiffer and more supportive.
While improving seat performance was a paramount concern, the team also boosted seat comfort by introducing Stingray’s first dual heating and cooling ventilation system for seats, overcoming packaging challenges in the process.
“While most Corvette drivers will find the GT seat perfectly comfortable and supportive, those who go to a track will appreciate the extra support offered by the Sport seat,” said Ryan Vaughan, design manager, performance car interiors. “They’re both a testament to the enormous amount of work that went into them. These are the best seats Corvette has ever had.”
Driver-oriented technologies
At the core of the Corvette Stingray’s driver-focused technologies is the cockpit-mounted Driver Mode Selector, which allows drivers to optimize the car for their driving preference and road conditions via five settings: Weather, Eco, Tour, Sport and Track.
“The all-new Corvette Stingray is really three cars in one: It provides the comfort and functionality of a long-distance GT car, the connectedness and infotainment of a daily driver and the acceleration, grip and braking of a capable track car,” said Harlan Charles, product manager. “With the Driver Mode Selector, we wanted to give drivers an easy way to tailor virtually every aspect of the car to fit their driving environment. The result is a more rewarding, more confident experience, whether you’re commuting in a downpour or charging through the corkscrew at Laguna Seca.”
The Driver Mode Selector is easy to use via a rotary knob near the shifter. The Tour mode is the default setting for everyday driving; Weather mode is designed primarily for added confidence while driving in rain and snow; Eco mode is for achieving optimal fuel economy; Sport mode is for spirited road driving and Track mode is for track use.
“Early in the development process, we spent time on the track, driving Corvettes hard. That experience shaped many parts of the interior, such as the instrument display in Track mode,” said Vaughn. “At 120 mph, you experience a sort of tunnel vision, as you concentrate on the next turn. At that moment, you don’t need to know the next song playing on the radio.”
Twelve performance parameters are adjusted with the selection of each mode, including:
- Gauge cluster configuration: The Tour, Eco and Weather modes feature displays for trip data, audio and navigation; Sport mode shows classic, easy-to-read sports car gauges; and Track mode’s configuration shows a gauge design based on the Corvette Racing C6.R race car display with lap timer
- ETC (Electronic Throttle Control): Adjusts the throttle input curve for the selected mode for improved responsiveness
- Paddle-shift automatic transmission : Adjusts shift comfort and shift points
- Active Fuel Management: in normal mode, the LT1 engine uses V-8 power; in Eco mode the engine can operate in V-4 mode to improve fuel economy until aggressive acceleration is called for
- Exhaust (active exhaust system): The system adjusts the timing of the electronically controlled exhaust valves to enhance audible feedback from the V-8 depending on the drive mode
- Electronic limited-slip differential (Z51): Adjusts the rate at which the limited slip engages, to balance between steering response and stability in different driving conditions; more aggressive performance in Sport and Track modes
- Steering: Assist effort is adjusted in the modes to provide the driver with the correct steering feel for the driving condition
- Magnetic Ride Control: Adjusts shock damping based on road conditions, from optimized comfort to performance driving
- Launch control: Available in Track mode for manual and automatic transmissions, providing maximum off-the-line acceleration
- Active handling (StabiliTrak stability control): A “competitive” setting is available in Sport and Track modes and is more suited for on-track conditions. It can also be disabled, giving the driver complete control
- Traction control: Weather mode tailors traction control and engine torque for driving in inclement conditions
- Performance Traction Management: Available in Track mode and offers five settings of torque reduction and brake intervention for track driving.
Three configurable displays, including a pair of eight-inch screens and color head-up display, deliver personalized information and convey the different performance parameters of each drive mode.
The two eight-inch screens offer excellent visibility in direct sunlight, with 650 cd/m2 of brightness for the one integrated into the instrument cluster and 1,000 cd/m2 of brightness for the one in the center stack, making them among the brightest screens in the industry. The screen in the center stack also features touch-screen control with gesture recognition and can be lowered to reveal a hidden storage compartment that includes a USB input for device charging or uploads.
The Corvette Stingray delivers an advanced infotainment system, featuring Chevrolet MyLink and high-definition radio, as well as enhanced OnStar with 3D navigation maps. An additional USB port in the center console, a stand-alone audio input jack and an SD card slot provide seamless connectivity.
An available premium 10-speaker audio system includes a bass box and two subwoofers – and speakers with rare-earth magnets that deliver greater sound quality with reduced weight and size
Every line counts on Corvette Stingray’s functionally elegant exterior
Corvette Stingray’s provocative exterior styling is as functional as it is elegant, said Ken Parkinson, executive director of global design.
“Developing a new Corvette, while every designer’s dream, is not an easy task,” Parkinson said. “The goal was a bold design statement that embraced the advanced technology of the car, while enhancing its overall performance in everything from the wind tunnel to the track. The result is a new Corvette Stingray – a fantastic car that breaks new ground yet remains true to the fundamental elements that make a Corvette a Corvette.”
While no single detail is repeated from previous generations, the new Corvette Stingray includes the distinctive profile defined by a long dash-to-axle ratio – a low, lean proportion emphasized even more on the convertible – and the greenhouse evoking the canopy of a fighter jet with dual-element taillamps. On this foundation, designers built a form vocabulary from two very different sources: aerospace and nature.
“For the new Corvette to be called a Stingray, it had to deliver an incredible, purposeful visual impact – just as the original did in 1963,” said Tom Peters, exterior design director. “That visual impact is evident in fighter jets and the Stingray animal itself. Their beauty comes from their purpose, designed to cut through air or water as quickly and efficiently as possible. As with aircraft and living forms, every surface of the Corvette Stingray is purposeful, executed with beauty and proportion.”
Lighting is a signature element of the Corvette Stingray’s design and reinforces its high-tech aesthetic. At the front, indirect white LED lamps form a distinctive daytime styling cue. They are set in black-chrome lamp housings with standard HID projector headlamps. The turn signals feature edge-lit amber LED lighting.
All-new, dual-element taillamps represent the greatest departure from tradition and are among the car’s most dramatic elements. The three-dimensional, sculpted lenses house innovative indirect LED lighting. The state-of-the-art lighting uses hidden LED lamps that cast their light up from the bottom of the housing into a reverse reflector, creating an even glow. LED lamps are also used for the white backup lamps. The taillamps integrate functional aircraft-style air outlets for the available differential and transmission coolers.
“From the front or rear, the signature lighting brings the new Corvette to life,” said Peters. “It looks beautiful, intriguing, and more than a little intimidating. It gives the Corvette a nighttime appearance unlike anything else on the street. ”
The Corvette Stingray convertible features an all-new, fully electronic top that can be lowered remotely using the key fob. The top can also be opened or closed on the go, at speeds of up to 30 mph (50 km/h). Its folding mechanism is all-new and enables the top to be lowered in 21 seconds.
With the top up, the convertible is designed for a refined driving experience. A thick, three-ply fabric top, along with sound-absorbing padding and a glass rear window, contributes to a quiet cabin and premium appearance.
With the top down, the Corvette Stingray’s signature profile is further accentuated. Behind the seat backs, dual black trim panels enhance the character lines of the tonneau cover. Corvette Stingray’s signature “waterfall” design originates in the valley between the seats, bringing the exterior color into the interior.
When it comes to aerodynamics, the new Stingray is in a league of its own. Advanced computer-aided modeling programs predict and track airflow over, under and through the new Corvette’s body. Engineers and designers also relied on data gleaned from the Corvette Racing program – the most successful program ever in the American Le Mans Series and the 2012 GT class champion – to help balance front and rear grip for high-speed stability.
Many hours were spent in the wind tunnel hand-sculpting surfaces for aesthetics and performance. Functional exterior elements on all models include a new grille/radiator arrangement, hood vents and front fender cove vents. Venting air out of the hood reduces total front-end lift for improved steering response at high speeds, while the fender vents relieve underhood air pressure to reduce aerodynamic drag.
All Corvette Stingray models with the Z51 package also feature integral coolers for the rear differential and transmission (the transmission cooler is also included with the optional automatic transmission). For coupe models, the air intakes are integrated on the rear quarter panels, similar to the NACA ducts on the Corvette Racing C6.R. For convertible models, the air intakes are integrated into the underbody.
Airflow through the differential and transmission heat exchangers exits through the aircraft-inspired taillamp vents and lower-rear fascia air outlets. The Z51 Performance Package also includes brake-cooling ducts, a unique rear spoiler and additional air deflectors for enhanced track capability.
“Every square inch of the 2014 Corvette’s exterior is designed to enhance high-performance driving ,” said Kirk Bennion, exterior design manager. “The team delivered a great balance of low drag for efficiency and performance elements for improved stability and track capability – all in a sculpted design that excites in all the ways that a Corvette has for six decades.”
Engineered to race, built for the road
Both coupe and convertible versions of the new Corvette Stingray take advantage of lightweight materials, advanced manufacturing techniques and technology transfer from the Corvette Racing program to produce an ideal 50/50 weight balance and to deliver world-class power-to-weight ratios.
The technologically advanced foundation is an all-new aluminum frame structure that is 99 pounds (45 kg) lighter, and is 57-percent stiffer than the previous-generation convertible. The result is a frame that is so strong, no structural reinforcements are needed for the convertible model. The only changes are limited to accommodations for the folding top and repositioned safety belt mounts.
Compared to the previous generation, which used continuous hydroformed main frame rails with a constant 2mm wall thickness, the new Corvette’s frame features main rails composed of five customized aluminum segments, including aluminum extrusions at each end, a center main rail section and hollow-cast nodes at the suspension interface points. Each segment’s gauge varies in thickness from 2mm to 11mm, tailored – along with the shape – by the simulation software to optimize the strength requirements for each frame section with minimal weight.
The aluminum frame is manufactured using innovative manufacturing processes at GM’s Bowling Green, Ky., assembly plant. The state-of-the-art facility employs several advanced joining technologies to ensure dimensional accuracy within 0.75 mm. Each frame features:
- 354 spot-welds using a GM-patented process that uses a unique electrode designed specifically for aluminum
- 188 Flowdrill-machined fasteners, which are installed by a high-speed drill that extrudes the frame material to create a strong, integral collar that is tapped for bolt-on fasteners
- 113 feet of structural adhesives, used in conjunction with welding and fasteners to increase overall frame stiffness
- 37 feet of laser welds, which join frame sections via a precise beam of high energy that minimizes heat beyond the weld area for improved structural accuracy.
The frame’s greater strength and lower weight are complemented by chassis elements also designed for low-mass strength, including hollow-cast aluminum front and rear cradles that are approximately 25-percent lighter and 20-percent stiffer than the solid cradles used on the previous structure.
The innovative use of materials includes a standard carbon fiber hood on all Corvette Stingray models, and carbon fiber roof panel on all coupes. In addition, underbody panels are created with carbon-nano composite technology, an advanced blend of traditional composite material and carbon fiber for reduced weight and improved strength. Fenders, doors, rear quarter panels and the rear hatch panel are made with lighter-density Sheet Molded Compound than the previous generation.
More power with greater efficiency
The lightweight elements of the Stingray contribute to the ideal 50/50 weight balance. Combined with its estimated 450 horsepower (335 kW), the new Corvette delivers a better power-to-weight ratio than the Porsche 911 Carrera or Audi R8.
Those 450 horses are generated by an all-new LT1 6.2L Small Block V-8 engine, which also produces an estimated 450 lb.-ft. of torque (610 Nm). More importantly, it generates 50 lb.-ft. more low-end torque than the previous 6.2L engine, matching the 7.0L LS7 engine from the 2013 Corvette Z06 from 1,000 to 4,000 rpm.
The engine’s performance comes from combining advanced technologies such as direct injection, Active Fuel Management and continuously variable valve timing with an advanced combustion system. More than 10 million hours of computational analysis went into the new Small Block’s design, including more than 6 million hours alone on the combustion system.
The LT1 is backed by a choice of active exhaust systems that are less restrictive than the previous generation, due in part to an increase in diameter from 2.5 inches to 2.75 inches. The standard system offers a 13-percent improvement in airflow and features a pair of butterfly valves that contribute to greater refinement at cruising speeds when the engine is operating in fuel-saving V-4 mode.
An available dual-mode active exhaust system offers a 27-percent improvement in airflow. It features two additional valves that open to a lower-restriction path through the mufflers. When open, these valves increase engine performance and produce a more powerful exhaust note.
In Europe, the LT1 is offered exclusively with a seven-speed manual with Active Rev Matching. In other global markets, a six-speed paddle-shift automatic transmission is also offered. The Corvette retains its distinctive rear transaxle layout for optimal weight balance.
The seven-speed manual incorporates rev-matching technology for upshifts and downshifts. This driver-selectable feature can be easily engaged or disengaged via paddles on the steering wheel. The seven-speed is used with a new dual-mass flywheel and dual-disc clutch, which deliver greater shift quality and feel through lower inertia. The transmission with the Z51 Performance Package includes specific close-ratio gearing for more aggressive driving.
“Active Rev Matching makes the new Corvette easier and more fun to drive in performance conditions,” said Jeuchter. “It anticipates the next gear selection and electronically ‘blips’ the throttle to match engine speed for a seamless gear change.”
The paddle-shift six-speed automatic is optimized for use with Active Fuel Management and features a lower-inertia torque converter for improved shift quality and shift speeds. In addition, shift feel and shift points can be adjusted through the Driver Mode Selector.
More direct, more connected driving feel
The new Corvette Stingray’s chassis and suspension are designed to take advantage of the lighter, stiffer structure. The reduced structural flex allowed engineers to more precisely tune the suspension and steering for a more nimble and responsive driving experience. The components and their calibrations – from the brake size and damper rates to the steering system – are identical between coupes and convertible.
“An important goal for the team was to create a more intimate and connected driving experience for the new Corvette Stingray,” said Mike Bailey, chassis vehicle system engineer. “Because they share common chassis tuning, power-to-weight ratios and structural rigidity, the coupe and convertible feel almost identical behind the wheel.”
While the Corvette Stingray retains the racing-proven short/long-arm suspension design, front and rear, the components are all-new. Improvements to the suspension include hollow lower control arms that save approximately nine pounds (4 kg) per vehicle and new aluminum rear toe links that save 2.4 pounds (1.1 kg) over previous steel links.
The Corvette Stingray rides on new 18 x 8.5-inch front and 19 x 10-inch rear wheels, while models with the Z51 Performance Package roll on 19 x 8.5-inch front and 20 x 10-inch rear forged aluminum wheels. New Michelin Pilot Super Sport run-flat tires developed specifically for the seventh-generation Corvette deliver comparable levels of grip than the wider tires of previous models.
As a result, the Corvette Stingray with the Z51 Performance Package is capable of 1g in cornering acceleration – comparable to the 2013 Corvette Grand Sport. Significantly, that is achieved with narrower and lighter wheels and tires. The reduced “footprint” reduces rolling resistance, steering effort and road noise , contributing to a more nimble feel, more immediate steering response and greater touring comfort and efficiency.
Dimensionally, the new Corvette’s wheelbase is approximately an inch longer than the previous generation, with front and rear tracks that are almost an inch wider. Those changes provide a more stable feel, particularly at high speeds, while the turning radius is decreased by approximately two feet for greater maneuverability in tight turns.
The Corvette Stingray features standard 35mm-piston Bilstein monotube shocks that connect to dual-path aluminum shock mounts that separate the shock rod and shock body load paths. The Z51 Performance Package comes with 45mm-piston Bilstein dampers for more aggressive body control and track capability. Z51 is available with the third-generation Magnetic Ride Control, which features a new twin-wire/dual-coil damper system that reacts 40 percent faster, enabling improved ride comfort and body control.
The new electric power steering system offers variable ratios and variable effort to tailor responsiveness and feel for each driving situation. It also delivers more precise control and feedback to the driver, along with greater variability of effort for high-performance driving and greater on-center sensitivity and linearity. Steering feel was further improved by increasing steering column stiffness by 150 percent, increasing intermediate shaft torsional stiffness by 600 percent, and mounting the steering gear to the front cradle structure. As a result, the steering system is five times stiffer than the previous generation.
A smart electronic limited-slip differential (eLSD) is included in the Z51 Performance Package and continuously makes the most of the torque split between the rear wheels. The system features a hydraulically actuated clutch that can infinitely vary clutch engagement and can respond from open to full engagement in tenths of a second. It shifts torque based on a unique algorithm that factors in vehicle speed, steering input and throttle position to improve steering feel, handling balance and traction.
“The electronic limited-slip differential transforms the Stingray by optimizing handling for the driving situation,” said Bailey. “By continuously modulating the torque split between the rear wheels, the eLSD can improve traction accelerating out of corner, improve stability on the highway and enhance steering turn-in and responsiveness.”
The eLSD is fully integrated with StabiliTrak and Performance Traction Management systems. Its calibrations vary among three modes, based on the Drive Mode Selector setting:
- Mode 1 is the default setting for normal driving and emphasizes vehicle stability
- Mode 2 is engaged when electronic stability control is turned off in the Sport or Track modes. This calibration enables more nimble turn-in and traction while accelerating out of a corner
- Mode 3 is automatically selected when Performance Traction Management is engaged. This calibration has the same function as Mode 2, but is fine-tuned to work with Performance Traction Management.
Standard Brembo brakes, with four-piston fixed calipers derived from racing, deliver exceptional stopping power on the street or track. System highlights include:
- 12.6-inch (320 mm) front rotors and 13.3-inch (338 mm) rear rotors are standard and have 35-percent more swept area than previous-generation brakes. Consequently, stopping distance is improved 9 percent
- Dual-cast, slotted 13.6-inch (345 mm) front rotors and 13.3-inch (338 mm) slotted rear rotors are included with Z51 Performance Package. They have 6-percent more swept area than the previous-generation Grand Sport and are cooled front and rear for improved track capability. Consequently, stopping distance is improved 5 percent
- All brake packages have fixed front and rear calipers that are stiffer for more even pad wear, reduced drag and improved modulation.

2014 CORVETTE STINGRAY CRANKS OUT 460 HORSEPOWER
The 2014 Corvette Stingray’s all-new LT1 6.2L V-8 engine is SAE-certified at 460 horsepower (343 kW) at 6,000 rpm and 465 lb-ft of torque (630 Nm) at 4,600 rpm, with the available performance exhaust system, Chevrolet announced today.
The Stingray is SAE-certified at 455 horsepower (339 kW) and 460 lb-ft (624 Nm) with the standard exhaust system. They are the highest standard power ratings ever for the Corvette, delivered with efficiency that is expected to exceed 26 mpg on the highway.
“The 2014 Corvette Stingray’s LT1 engine is a triumph of advanced technology, delivering more power and torque than ever before with greater efficiency,” said Jordan Lee, Small Block chief engineer.
“The LT1’s performance complements the Corvette’s low mass with a tremendous feeling of power that builds as the rpm climbs. Drivers will experience more power and acceleration than ever before with the standard engine – in fact, its power and torque surpass many uplevel engines offered by competitors.”
At 74 horsepower per liter, the LT1 has greater power density than the C6 Corvette’s LS3 6.2L engine and even the C6 Z06’s racing-derived 7.0L LS7. It also produces comparable torque to the LS7 – up to 4,700 rpm – and its peak torque is within 5 lb-ft of the 7.0L engine. That torque is generated early and sustained across the rpm band, with 316 lb-ft available at only 1,000 rpm and 90 percent of peak torque available from 3,000 rpm to 5,500 rpm – giving the lightweight Corvette Stingray excellent acceleration at all speeds.
Chevrolet estimates the Corvette will run from 0 to 60 mph in less than four seconds.
The new LT1 engine’s high output, and high power density and efficiency are due to several advanced technologies, including direct injection, Active Fuel Management and continuously variable valve timing, which support an advanced combustion system.
Direct injection is a primary contributor to the engine’s combustion efficiency, ensuring a more complete burn of the fuel in the air-fuel mixture. That’s achieved by precisely controlling the mixture motion and fuel injection spray pattern. Direct injection also keeps the combustion chamber cooler, which allows for a higher compression ratio. Emissions are also reduced, particularly cold-start hydrocarbon emissions, which are cut by about 25 percent.
Active Fuel Management, or cylinder deactivation, is a first-ever application on Corvette. It helps save fuel by imperceptibly shutting down half of the engine’s cylinders in light-load driving. Continuously variable valve timing is refined to support the LT1 AFM and direct injection systems to further optimize performance, efficiency and emissions.
These technologies support the all-new, advanced combustion system, which incorporates a new cylinder-head design and a new, sculpted piston design that is an integral contributor to the high-compression, mixture motion parameters enabled by direct injection.
Additional engine features include:
- Advanced oiling system with oil-spray piston cooling and available dry-sump oiling
- Engine-mounted, camshaft-driven fuel pump to support the direct injection system
- Intake manifold with “runners in a box” design that allows for high-efficiency airflow packaged beneath the Corvette’s low hood line
- High-flow, four-into-one exhaust manifolds based on the design of the LS7 engine.
Small Block legacy
The 2014 Corvette Stingray’s LT1 engine is the fifth generation of the Small Block engine family, which debuted in the Corvette in 1955. It displaced 4.3L (265 cubic inches) and was rated at 195 horsepower, drawing air and fuel through a four-barrel carburetor. Five years later, Small Block power helped Corvette secure its first victory at the 24 Hours of Le Mans.
In 2012, the Small Block-powered Corvette Racing C6.R beat Ferrari, BMW and Porsche to sweep the drivers’, team, and manufacturer championships in production-based American Le Mans Series GT class. These championships make Corvette Racing the most successful team in ALMS history, with a total of 77 class wins, eight drivers’ championships, and nine manufacturer and team championships since 2001.
The 2014 Corvette Stingray coupe goes on sale this fall, with a convertible following by the end of the year – each sharing an all-new aluminum frame structure and enhanced chassis, as well as completely new exterior and interior designs.
CORVETTE STINGRAY: 3.8 SECONDS FROM 0 TO 60 MPH TURNS IN 2:51.8 LAP AT VIRGINIA INTERNATIONAL RACEWAY
Jun 20, 2013 – Chevrolet released official performance estimates today for the 2014 Corvette Stingray, the most capable standard Corvette ever. Equipped with the available Z51 Performance Package, the new Stingray is capable of accelerating from 0 to 60 mph in 3.8 seconds, braking from 60 to 0 in 107 feet, and sustaining 1.03 g in cornering.
Cumulatively, the acceleration, cornering and braking capability of the Corvette Stingray enabled it to lap the Virginia International Raceway’s (VIR) 4.2-mile “Grand Course” in 2:51.78.
“For the new Stingray, we set out to elevate every aspect of the Corvette’s performance,” said Tadge Juechter, Corvette chief engineer. “Considered alone, the acceleration, braking and cornering performance of the Corvette Stingray is truly impressive. More significant is how well they work together, resulting in a lap time at VIR that places the new Stingray in the upper echelon of all sports cars.”
2014 Corvette Stingray Z51 | |
Acceleration from 0-60 MPH | 3.8 seconds |
¼ mile acceleration | 12 seconds @ 119 mph |
Braking distance from 60 to 0 MPH | 107 feet |
Maximum lateral acceleration | 1.03 G |
VIR ‘Grand Course’ Lap | 2:51.78 |
The lap around VIR was conducted in Stingray equipped with the available Z51 Performance Package and Magnetic Ride Control. The vehicle that conducted the lap was modified only with safety features like a racing seat and harness, and fire extinguisher system.
“The new Stingray constantly communicates feedback to the driver, which makes you feel incredibly confident behind the wheel,” said Jim Mero, Corvette vehicle dynamics engineer. “That confidence encourages you to attack each corner because the Stingray drives so well: the tire grip is incredible; the steering response is some of the best I’ve ever experienced; the Magnetic Ride dampers allow little body roll through the corner, while still soaking up the rumble strips when you clip the apex,” he said. “It’s just addictive on the track.”
The 2014 Corvette Stingray coupe goes on sale in the third quarter of 2013 for a suggested starting retail price of $51,995, excluding tax, title, and license fees. The $2,800 Z51 Performance Package includes an electronic limited-slip differential; dry-sump oiling system; integral brake, differential and transmission cooling; as well as a unique aero package that further improves high-speed stability. Magnetic Ride Control with Performance Traction Management is a $1,795 option. A Corvette Stingray equipped like the test car used at VIR would cost $56,590.

2014 CORVETTE STINGRAY: 69 UNIQUE SOURCES COVERED IN THREE ADVANCED CLUSTER DISPLAY MODES
69 unique sources covered in three advanced cluster display modes
Aug 12, 2013 – The advanced cluster display in the 2014 Corvette Stingray can provide up to 69 unique sources of information, ranging from an interactive performance timer to a tire tread temperature display. The crisp and bright display features make this information easily accessible via three configurable modes that prioritize information for daily commuting, weekend canyon carving and track events.
Flanked by three analog gauges for speed, fuel level, and engine-coolant temperature, the eight-inch liquid-crystal display screen in the center of the cluster is organized into sport, tour and track themes that change with the Driver Mode Selector. Each display theme is designed for a specific driving scenario and can be configured through applications found in the “app tray.”
“The new Corvette Stingray features many advanced technologies, so our challenge when designing the driver’s displays was to ensure that those technologies could be easily found in common driving scenarios,” said Jason Stewart, General Motors interaction designer.
“The touring theme places more emphasis on multimedia and infotainment; the sport theme emphasizes performance features with a prominent shift indicator and a large radial tachometer; track theme offers a race-inspired layout containing a sweeping tachometer, Corvette racing inspired shift lights and permanent lap-time displays,” Stewart said. “Each of these three themes can also be configured so that drivers can personalize their experience in the Stingray.”
Here are 10 configurable display features that will help drivers realize the Stingray’s capabilities:
1. Tour theme – Displayed when the Stingray is in Weather, Eco, or Tour drive mode, this is the most modern display, providing essential vehicle information drivers want for commuting or long-distance driving and includes key vehicle information and multimedia displays
2. Sport theme – Displayed when the Stingray is in Sport mode, this theme is designed to recall the classic sports-car experience, with a single, radial tachometer dominating the display
3. Track theme – Inspired by the cluster of the Corvette Racing C6.R, this theme prioritizes the information vital for a successful track outing, including a “hockey stick” style tachometer, large gear indicator and shift lights
4. Adjustable redline – All themes feature an adjustable redline that shows the suggested maximum engine speed as low as 3,500 rpm when the engine is cold
5. Tachometer ‘halo’ – The Sport theme features a ring around the tachometer that glows from yellow to amber to red as engine rpms increase
6. Shift lights – The track theme features shift lights influenced by the C6.R, which illuminate from the outside-in, transition from green to yellow to blue and flash at redline providing an easy-to-see shift notification at high speeds
7. Friction-bubble/cornering force – The friction bubble that displays lateral and longitudinal G-forces allows drivers to measure how close they are to the Stingray’s limits
8. Tire temperature gauge – Leveraging the existing Tire Pressure Monitoring System, this patented system informs the driver as the tires warm up from cold to warm to hot, with hot being the optimal temperature for peak grip and track performance
9. Acceleration timer – The interactive timer features programmable start/end speeds, which enable drivers to measure any acceleration run, from a traditional 0-60 mph to acceleration from 70-100 mph in top gear
10. Lap timer – Shows current, previous and best lap times, enabling drivers to measure their consistency while lapping a road course
The 2014 Corvette Stingray coupe goes on sale in the third quarter of 2013.
